Once you find a way to automatically restart the system, you still have to decide if you should.
Assuming you have a UPS.
Does the UPS trigger the system to shutdown, and if so after what percentage of battery life is used?
Does the system just continue to run until the battery is dead?
Does the UPS restore power to the system if the battery is less than xx% charged?
Do you know how many power failures you have per year, and how many of these exceed the battery life?
If you do decide to automatically restart the system, you should make sure that you wait until the power supply is stable.
There is no UPS.
